摘 要: 当代MOMA工程结构存在多处设计难点,重点解决了纯地下室抗浮设计、地下结构超长不设缝及不均匀沉降协调设计、主体结构悬挑和收进超限、高位多塔楼连体和大跨度连廊的舒适度等多个问题。工程结构型式多样,包括钢筋混凝土结构、钢结构及型钢混凝土组合结构。工程设计中采用性能化抗震设计的思想,进行了整体结构的静力弹塑性分析,竖向地震时程分析,9个塔楼连体的非线性时程分析等,并通过合理的结构构造措施较好地进行了几种不同结构的相互结合,解决了工程设计的难点。 The structural design of Beijing Grand Moma faced many difficulties such as flotage of underground water, differential settlement of tower and annex,targe cantilever,setback of the structure,linked structure,and vibration of large span bridges.The engineers use reinforced concrete structure,steel structure and steel reinforced concrete structure in this project for different part.Performance based seismic design is adopted.Static plastic analysis of towers, vertical seismic analysis of cantilever and bridges,and nonlinear time history analysis of isolated structure are applied. By carefully design,the structure performance targets are fulfilled.
